How did England try to control trade with its American colonies?

The idea was mercantilism. By taxes, route acts, and assessments Britain endeavored to corner all exchange with the American settlements.
Clarification:
The monetary model of mercantilism was that the settlements were compelled to exchange just with the " mother" nation. The provinces would give a wellspring of crude materials and merchandise that must be sold to the " mother" nation. Consequently, the settlements would give a market to the fabricated results of the " mother" nation.
For Britain, it was a win. What crude materials that Britain couldn't utilize could be sold by English vendors for a benefit to different nations. Britain could control the expense and appoint an incentive to the crude materials from the provinces substantially less than the estimation of the products on a worldwide open market.
Britain could likewise set the costs for its fabricated items setting the esteem higher than what the provinces may have been e ready to get from different nations. The route demonstrations required all merchandise going to the provinces must be delivered in English hailed ships.
Assembling in the provinces was debilitated by the utilization of taxes and expenses on every made great created in the settlements. The levies and duties protected that the expense of made products from the provinces couldn't contend with the expense of fabricated merchandise made in Britain.
English income vessels endeavored to uphold the route demonstrations. Any endeavor to transport products in or out of the settlements not directed by Britain was viewed as the wrongdoing of sneaking. The route demonstrations were not totally effective in controlled exchange but rather these laws helped construct the hatred toward Britain that caused the progressive war.
